Export logs from ringserver as postgresql timeseries

ringserverstats

Parse ringserver reports, compute statistics and store in influxdb.

Installation

ringserverstats is distributed on PyPI https://pypi.org as a universal wheel.

    $ pip install ringserverstats

Postgresql preparation

CREATE ROLE resifstats WITH LOGIN PASSWORD 'md5xxxxxxxxxx';
CRATE DATABASE resifstats OWNER resifstats;
\c resifstats
CREATE EXTENSION timescaledb

Then go for the migrations :

$ yoyo apply --database postgresql://[e-mail]:5433/resifstats -m migrations

Docker

docker build -t ringserverstats:latest
docker run --rm -p 8000:8000 -e DATABASE_URI=postgresql://[e-mail]:5433/resifstats ringserverstats:latest

Usage

To work properly, this program needs the environment variable DATABASE_URI pointing to a valip postgresql URI

Command line interface

$ pip install --user ringserverstats
$ ringserverstats txlogs.log

Web application

For development :

cd webapp
FLASK_ENV=development FLASK_APP=webapp.py flask run

In production, use with gunicorn :

pip install gunicorn
cd ringserverstats
gunicorn -b 0.0.0.0:8000 webapp

To send date :

http localhost:8000 < txlogs.log
wget --post-file txlogs.log localhost:8000

Explanations

The TX logs from ringserver are metrics suitable for a timeserie database. The idea is to parse the logs, as in the exemple below, and to generate values to insert into an influxdb timeseries database.

The file grafana-dashboard.json can be imported into grafana to visualize this timeserie.

Events

The ringserverevents measure has several tags :

• network, station, location, channel : which data was requested
• geohash : location of the client in geohash format
• hosthash : a hash of the client ip (usefull to correlate the clients requests)
• city : an english city name

Grouping and downsampling

To achieve downsampling, we use timescaledb's continuous query.
